Description

Technical Field

[0001] This utility model belongs to the field of purification technology, and in particular relates to an air guide cover and purifier. Background Technology

[0002] Air purifiers, as essential home appliances for improving indoor air quality, rely heavily on efficient airflow system design for their core performance. The exhaust impeller, acting as the airflow power source, typically has an air guide shroud structure at its front or rear to guide airflow smoothly into the impeller's working area, improving intake efficiency, reducing wind noise, and optimizing overall aerodynamic performance. Existing air guide shrouds mostly employ a single ring structure or simple bracket support, offering limited functionality and primarily focused on airflow guidance. This fails to meet the comprehensive demands of modern air purifiers for high airflow, low noise, compact design, and multi-functional integration.

[0003] In practical applications, the air guide cover has some limitations: on the one hand, the connection between the air guide cover and the drive unit often relies on additional brackets or complex fasteners, resulting in a bulky structure; on the other hand, the wires used to connect components such as motors are usually in a free-suspension state or simply tied to the bracket, which are easily affected by airflow impact, vibration and wear, and may even become loose or short-circuited, posing safety hazards. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a simpler and more compact air guide cover.

[0005] The objective of this utility model can be achieved through the following technical solution: a wind guide cover, comprising:

[0006] Multiple coaxial and spaced-apart air guide rings, with their diameters gradually changing as they get closer to the outlet impeller, are used to guide air toward the outlet impeller.

[0007] The reinforcing parts are multiple in number and are distributed at intervals along the circumference of the air guide rings. Each reinforcing part is connected to all or at least part of the air guide rings.

[0008] When the air guide ring is provided with a connecting part for connecting with the drive part of the air outlet impeller, the air guide ring exhibits a gradual change in diameter as it gets closer to the air outlet impeller in a straight line.

[0009] In one of the aforementioned air guide covers, a mounting portion is also included. The mounting portion is annular and coaxially arranged with the air guide ring. The mounting portion is located outside the outermost air guide ring and there is a gap between them. The mounting portion is used to connect with the purifier housing. When the air guide ring is provided with a connecting portion for connecting with the drive portion of the air outlet impeller, the outermost air guide ring protrudes from the mounting portion along the axial direction of the air outlet impeller.

[0010] In one of the aforementioned air guide hoods, a connecting ring is provided inside the innermost air guide ring. Around the circumference of the connecting ring, multiple connecting plates are fixedly arranged at intervals on the outer ring wall of the connecting ring and connected to the innermost air guide ring. The number of connecting parts is multiple, and the multiple connecting parts are also distributed in a ring-shaped interval between the connecting ring and the air guide ring.

[0011] In one of the aforementioned air guide covers, the ends of some of the reinforcing parts are fixed to each other.

[0012] In one of the aforementioned air guide shrouds, the connecting ring and the air guide ring are located in the same plane along the axial direction of the air outlet impeller.

[0013] In the aforementioned air guide shroud, a wiring section is also included. The wiring section extends from the mounting section to the innermost air guide ring. The extension direction of the wiring section is perpendicular to the axis of the air outlet impeller. The wiring section includes a wiring cavity with an opening on the windward surface. The bottom wall of the wiring cavity is provided with an air passage groove. The inner side wall of the wiring cavity is provided with wire-blocking posts at intervals.

[0014] In one of the aforementioned air guide covers, a wire clamping cover is detachably installed on the wiring section of the mounting portion.

[0015] In one of the aforementioned air guide covers, a junction box fixed to the mounting portion is also included. A junction box has a junction cavity, and a through-hole cable outlet is provided on the junction box, which communicates with the junction cavity.

[0016] The aforementioned air guide cover also includes an air duct plate, which is used to fix to the purifier housing, and the mounting part is fixed to the air duct plate.

[0017] An air purifier, comprising the aforementioned air guide shroud.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) By setting multiple coaxial and axially arranged air guide rings, a gradual flow channel structure is formed between the multiple air guide rings, which can effectively guide the airflow smoothly into the outlet impeller, significantly improve the uniformity and continuity of the intake airflow, and improve the overall air volume and energy efficiency. Moreover, it also realizes the organic integration of air guiding function and mechanical connection function. In particular, the connecting part set on the air guide cover makes the air guide cover itself also serve as the installation support for the drive component. It eliminates the need for independent brackets or additional fastening components used to connect the motor in the traditional structure, and improves the integration of the drive system and the air duct structure;

[0020] (2) It also includes a wiring section, which extends from the mounting section to the innermost air guide ring. The extension direction of the wiring section is perpendicular to the axis of the air outlet impeller, forming a radial wiring channel from the outside to the inside. This structure provides a dedicated guide path for the wires or signal lines connected to the drive unit (such as motors), realizing the orderly arrangement of cables inside the air guide cover, and avoiding the cables from being messy and tangled or vibrating, wearing or even breaking due to airflow impact.

[0021] (3) The bottom wall of the wiring cavity is provided with an air passage groove, which runs through the bottom of the wiring cavity and is connected to the air inlet channel. When the air guide shroud is working, the external airflow can not only enter from the main channel between the air guide rings, but also flow into the interior through the air passage groove, which effectively increases the air inlet area and improves the air intake of the whole machine.

Detailed Implementation

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] like Figures 1-6 As shown, an air guide shroud includes:

[0032] Multiple coaxial and spaced-apart air guide rings 100, which exhibit a gradual change in diameter as they get closer to the outlet impeller, are used to guide air toward the outlet impeller.

[0033] There are multiple reinforcing parts 101, which are distributed at intervals along the circumference of the air guide ring 100, and each reinforcing part 101 is connected to all or at least part of the air guide ring 100.

[0034] When the air guide ring 100 is provided with a connecting part 102 for connecting with the drive part of the air outlet impeller, the air guide ring 100 exhibits a gradual change in diameter as it gets closer to the air outlet impeller in a straight line.

[0035] The air guide shroud in this application is applied to an air purifier. By setting multiple coaxial air guide rings 100 arranged along the axial direction, the multiple air guide rings 100 form a gradually changing flow channel structure, which can effectively guide the airflow smoothly into the outlet impeller, significantly improving the uniformity and continuity of the intake airflow, and enhancing the overall air volume and energy efficiency. Moreover, it also achieves the organic integration of air guiding function and mechanical connection function. In particular, the connecting part 102 set on the air guide shroud makes the air guide shroud itself also serve as a mounting support for the drive component. This eliminates the need for a separate bracket or additional fastening components for connecting the motor in traditional structures, improving the integration of the drive system and the air duct structure.

[0036] As the diameter of the air guide ring 100 gradually decreases as it gets closer to the outlet impeller, the shrinkable structure provides the necessary space and structural adaptation conditions for setting the connecting part 102 for connecting the outlet impeller drive unit in the central area, thereby realizing the integration of the air guide shroud and the drive component.

[0037] Conversely, as the diameter of the air guide ring 100 gradually increases as it approaches the outlet impeller, it forms an expanding air guide channel, which can effectively increase the air intake area, enhance the ability to capture the surrounding airflow, and improve the air guide range and air intake efficiency.

[0038] Furthermore, the air guide cover also includes a coaxially arranged annular mounting portion 103. This mounting portion 103 is located outside the outermost air guide ring 100 and maintains a certain gap with it, used to stably connect the air guide cover to the purifier housing, achieving reliable fixation of the overall structure. The separate design avoids interference of the mounting portion 103 with the airflow channel of the air guide ring 100, which helps maintain the smoothness and guidance of the airflow. The connection between the mounting portion 103 and the air guide ring 100 can also be achieved through the reinforcing portion 101.

[0039] Specifically, when the air guide ring 100 is provided with a connecting portion 102 for connecting the exhaust impeller drive unit, the outermost air guide ring 100 protrudes from the mounting portion 103 along the axis of the exhaust impeller. This protruding structure extends the axial length of the air guide area, allowing the airflow to be guided and converged earlier when entering the air guide shroud, effectively expanding the effective air intake range and enhancing the ability to capture surrounding air, thereby significantly improving the air guide effect and the overall air intake volume.

[0040] Furthermore, the ring wall of the air guide ring 100 is parallel to the axial direction of the outlet impeller. This makes the air guide ring 100 form a straight or nearly straight cylindrical flow channel, which can efficiently and with low resistance guide the airflow entering the purifier axially, reduce turbulence and energy loss caused by sudden changes in airflow direction during the inflow process, and significantly improve the stability and permeability of the intake airflow.

[0041] An annular connecting ring 104 is provided inside the innermost air guide ring 100, and the outer ring wall of the connecting ring 104 is fixedly connected to the innermost air guide ring 100 by multiple connecting plates 105 evenly spaced along its circumference, forming a stable internal support structure. This enhances the structural rigidity and integrity of the central area of ​​the air guide shroud, effectively avoiding deformation or breakage caused by localized stress concentration, and maintaining structural stability, especially under high-speed airflow impact or long-term operation conditions.

[0042] Multiple connecting parts 102 are distributed in a ring at intervals between the connecting ring 104 and the air guide ring 100 (or directly integrated into the connecting ring 104), and the connecting parts 102 extend inward from the innermost air guide ring 100 or the connecting ring 104 along the axial direction of the air outlet impeller, forming a connection structure that actively extends towards the interior of the purifier. This extended connecting part 102 can surround and cover the drive unit, realizing a coaxial and tight connection between the air guide shroud and the air outlet impeller drive system.

[0043] The ends of some reinforcing parts 101 not only extend towards the innermost air guide ring 100, but also connect and fix with adjacent reinforcing parts 101, so that the multiple reinforcing parts 101 are no longer independent of each other, but form a continuous and cooperative support frame, which significantly improves the integrity and rigidity of the internal structure of the air guide shroud. This enhances the air guide shroud's ability to bear central loads (such as mechanical stress when the drive unit is connected), and improves the structure's torsional, compressive, and vibration resistance.

[0044] Along the axial direction of the air outlet impeller, the connecting ring 104 and the air guide ring 100 are located in the same plane, that is, they are basically flush or coplanar in the axial direction. This effectively shortens the force transmission path, so that the airflow load borne by the air guide ring 100 and the mechanical connection load borne by the connecting ring 104 can be distributed in the same axial plane, reducing the bending moment or torsional stress caused by structural misalignment, and significantly improving the overall structural stability and stress uniformity of the air guide shroud.

[0045] In addition, the flush arrangement of the connecting ring 104 and the air guide ring 100 in the axial direction helps to maintain the smoothness of airflow when passing through the central area, avoids the increase of local vortices or wind resistance caused by structural protrusions or depressions, and further optimizes the symmetry and stability of the intake airflow.

[0046] like Figure 1 , Figure 6 As shown, based on the above embodiment, it also includes a wiring section 200. The wiring section 200 extends from the mounting section 103 to the innermost air guide ring 100. The extension direction of the wiring section 200 is perpendicular to the axis of the air outlet impeller, forming a radial wiring channel from the outside to the inside. This structure provides a dedicated guiding path for the wires or signal lines connected to the drive unit (such as a motor), realizing the orderly arrangement of cables inside the air guide cover, and avoiding the cables from being messy and tangled or vibrating, wearing or even breaking due to airflow impact.

[0047] Specifically, the wiring section 200 is constructed as a semi-enclosed wiring cavity 203, forming a protected internal channel for accommodating and guiding the connecting wires of the drive unit. The bottom wall of the wiring cavity 203 is provided with an air passage 202, which extends through the bottom of the wiring cavity 230 and communicates with the air inlet channel. When the air guide shroud is in operation, external airflow can enter not only from the main flow channel between the air guide rings 100 but also flow into the interior through the air passage 202, effectively increasing the air inlet area and improving the overall airflow. Multiple wire-blocking posts 201 are spaced apart on the inner wall of the wiring cavity 203 to prevent the wire harness from slipping out. When the wire harness is arranged along the wiring cavity 203, the wire-blocking posts 201 effectively prevent it from slipping out or loosening during equipment operation due to vibration, airflow impact, or assembly disturbance, ensuring the stability and safety of the electrical connection. Furthermore, the wire-blocking posts 201 are staggered along the extension direction of the cable routing cavity 203, that is, adjacent wire-blocking posts 201 are alternately arranged on the inner walls of both sides of the cable routing cavity 203, and only one end is fixed to the cavity wall, forming a cantilever structure.

[0048] A cable management section 205 is fixedly installed inside the cable routing cavity 203. The cable management section 205 is provided with a cable management groove 206 with an opening at one end. The connecting wire can be inserted from the opening end and locked into the cable management groove 206 to achieve the positioning and organization of the connecting wire. Furthermore, a cable clamping cover 204 is detachably provided on the cable routing section 200. When the cable clamping cover 204 is assembled to the cable routing section 200, it covers the opening of the cable routing cavity 203 and clamps and fixes the connecting wire located in the cable management groove 206, preventing the connecting wire from shifting, rubbing or falling off due to vibration or external force during equipment operation.

[0049] Furthermore, the cable clamp cover 204 employs a detachable connection method (such as a snap-fit, screw, or magnetic structure), ensuring functionality while maintaining maintainability of the internal wiring of the cable routing cavity 203. Users or maintenance personnel can easily remove the cable clamp cover 204 when needed to inspect, replace, or re-lay out the cables, balancing aerodynamic performance and engineering practicality.

[0050] It also includes a junction box 300 fixed to the mounting unit 103. The junction box 300 has a cable management cavity 301 inside, used to accommodate and organize redundant cable segments left during assembly of the connecting wires to the drive unit. During the assembly and subsequent maintenance of the air purifier, a certain length of slack is usually left at the cable end for easy installation, disassembly, or adjustment of the air guide cover. The cable management cavity 301 provides dedicated storage space for these reserved cable segments, effectively preventing insulation damage, signal interruption, or short circuit risks caused by cable pressure, twisting, or friction. The junction box 300 has a through-hole cable outlet 305 connected to the cable management cavity 301, used to guide the connecting wire smoothly out of the cable management cavity 301 and into the purifier's main circuit system, or to connect the connecting wire to the drive unit.

[0051] The junction box 300 includes a box body 302 and a cover 303 detachably connected to the box body 302. A connecting post 304 is fixedly installed inside the box body 302. This connecting post 304 serves two purposes: firstly, it cooperates with the cover 303 to achieve detachable fixation (e.g., through snap-fit, thread, or interference fit); secondly, it also has a structural reuse function, acting as a winding post within the cable collection cavity 301, allowing connecting cables to be wound around it. It fulfills both the mechanical connection function of the cover 303, ensuring the sealing and structural stability of the junction box 300, and the cable winding structure for neatly winding and fixing the reserved connecting cables, preventing the cables from loosely moving, tangling, or being pulled by external forces within the cable collection cavity 301.

[0052] Once the cover 303 and the body 302 are assembled, they cover the cable outlet 305 and form a seal around it, effectively preventing external airflow from entering the equipment housing through the cable outlet 305.

[0053] Furthermore, it also includes an air duct plate 400, which serves as a common mounting base for the air guide shroud assembly and is used for fixed connection with the purifier housing. The mounting part 103 of the air guide shroud and the junction box 300 are both pre-fixed to the air duct plate 400, forming a modular unit that can be assembled as a whole. This simplifies the installation process of the air guide shroud, wiring system, and related components during the overall assembly of the purifier, improving assembly efficiency and positioning accuracy.

[0054] Specifically, when the air purifier is equipped with multiple air outlet impellers (such as a dual-duct or multi-fan system), multiple air guide covers can be installed, each with a corresponding mounting part 103. All mounting parts 103 are fixed to the same air duct plate 400. The overall positioning and fixing are completed by a single air duct plate 400, which greatly simplifies the assembly complexity of the multi-fan structure.
